Dear embedded software enthusiasts,

In a Mind Tech Talk, a Mind colleague guides the participants through a specific technical topic with a Q&A at the end. These take place every month, alternating between Tuesdays and Thursdays. These sessions are open to anyone interested, so feel free to forward this invite to others! You can find the overview of the Tech Talks on our blog.

Upcoming Mind Tech Talk

A MIDI controller on top of the Zephyr USB device_next stack
By Titouan Christophe
Thu 08 May 2025 | 12h-13h CET

This talk explores the journey of implementing and upstreaming USB-MIDI support in Zephyr RTOS, starting from a custom music controller project. We'll first look at the MIDI (Musical Instrument Digital Interface) specification from the 1980's and how it evolved into MIDI2 recently.

We will then dive into practical consideration for actually exchanging MIDI data with a USB host. We will look deeper into Zephyr's USB device_next stack; the newer, more dynamic way of implementing actual USB devices using this fancy kite-stamped RTOS.

If you are not familiar with it, this is also an occasion to have a glimpse at the device model and how Zephyr applications and drivers are structured.

Everyone is welcome to attend, and questions are warmly encouraged. You don't need to register, just join us on Thursday 08/05 at 12h.
